AI Image Detectors
An AI image detector estimates whether an image was generated by AI. It shares the word "detector" with AI content detection — our main ranking — but it examines a different medium with different methods.
Why this page exists
"AI detector" now spans text and images, and the two markets are routinely conflated. A tool's accuracy on machine-generated text tells you nothing about its accuracy on machine-generated images — different signals, different failure modes, different evidence. Our main AI detection ledger covers text detection only, so this page keeps the image sense from contaminating it.
Where the two markets touch
Two tools in our 2026 ledger also advertise image detection on their own pages: Winston AI states it offers an AI image detector covering outputs from tools including ChatGPT, Nano Banana, and Midjourney, and Pangram lists image detection alongside its text detection. These are vendor-stated features, and vendor feature lists are not independent evidence — the same claim/evidence rule from our specification applies here.
What AI image detection is evaluated on
- Generator coverage — which image models' outputs it is tested against.
- Edit robustness — behavior on cropped, compressed, or partially edited images.
- False-positive behavior — how often real photographs are flagged.
- Evidence transparency — whether any testing is independent and reproducible.
These are criteria, not product claims — we have not verified any vendor's image detection against them, and this page makes no accuracy claims about any product.
FAQ
Is an AI image detector the same as an AI text detector?
No. An AI image detector estimates whether an image was generated by AI. An AI text detector estimates whether a text was generated by AI. They examine different media with different methods, and evidence about one says nothing about the other.
Do the tools in this ranking also detect AI images?
Some vendor pages state that they do: Winston AI advertises an AI image detector covering outputs from tools including ChatGPT, Nano Banana, and Midjourney, and Pangram lists image detection alongside its text detection. These are vendor-stated features. Our 2026 ledger scores text-detection evidence only.
